this book really only works well with the Can Seo tv programme which is now available on Youtube. the combinagtion of the book, the programme and an evening class based on the book is very helpful in deed. 'S toil leam seo. Tha gu mhath, tappadh leibh.
A fairly short and basic introduction to Scottish Gaelic. It's also very dated (the fishermen wearing flares on the pixellated cover should give you a clue). It used to be published with cassettes, and accompanied a TV series - no idea if these can be found on Youtube.
The strong point of the book is it concentrates on the spoken language, and so a lot of the stuff in it is very colloquial, to the point which a lot of the vocabulary given in it is basically English written in Gaelic spelling.
If you're one of a handful into the Gaelic nostalgia market, get this, but check out some of the newer options.
